Hi, I'm trying to get a list of addresses from http://tatts.com/racing/outletsearch based on a list of postcodes (zip codes) and states. For example, I'm looking for State = 'Northern Territory' and Postcode = '0800'. The list I'm working off is about 500 long so I was hoping to find a way to script this in R. I regularly us readLines and the XML library to scrape

I'm aware that this is probably a pretty basic

Hi, I would appreciate if someone can give me a pointer on how to save a webpage programmatically using R. For example, let say I have this webpage open in my browser: http://www.bseindia.com/stock-share-price/dabur-india-ltd/dabur/500096/ When manually I save this page, I just press Command+S (using Mac) and then this page get saved in hard-disk Now I want R to mimic this same job that I do

I am trying to download a bunch of files from a server, for which I am using download.file( ) within a for loop. The script is working fine except until download.file hits a URL which has no file, at which point it exits. I want to change this behavior to simple log the failure and maintain state within the for loop and iterate to next. I read about try / tryCatch but am having trouble

Hi, I am starting coding in r and one of the things that i want to do is to scrape some data from the web. The problem that I am having is that I cannot get passed the disclaimer page (which produces a session cookie). I have been able to collect some ideas and combine them in the code below but I dont get passed the disclaimer page. I am trying to agree the disclaimer with the postForm and write

Gabor, Thanks much. Your solution is elegant. My overall scheme is to take present date, and check whether it is a weekend, if not, then create a string based on the date, to concatenate into a url link for download.file( ). The files I need to download have a part which is in the format: mmddyy. I am working to make myself a system to connect to exchanges, and download end of day files from

Hi, I am having trouble submitting a form using the RCurl package. My code runs without errors but doesn't return the table I am after. I have a feeling it is because there are 2 submit buttons on the page and I'm not hitting the right one. I have tried everything I can think of to submit the form correctly but with no luck. My current code is as follows. library(RCurl) library(XML)

Dear R-Help, I am looking into using the Open Calais web service (http:// sws.clearforest.com/calaisViewer/) for text mining purposes. I would like to use R to post text into one of the forms on their website. In package RCurl, there is a function called postForm(). This sounds like it would do the job. Unfortunately the URL used in the example is no longer valid (i have emailed the maintainer

Hi everybody, I think that I am missing something fundamental in how strings are passed from a postForm() call in R to the curl or libcurl functions underneath. For example, I can do the following using curl from the command line: $ curl -d "Archbishop Huxley" "http://www.datasciencetoolkit.org/text2people"

I am working on a simple pilot project comparing the capability of SQL, SAS and R to perform a rolling mean per the following instructions.
